First of all my husband js with her whole night. Not with me:( second she is growing and i want her sleep in her room with her bro or sis that will arrive afer 6 months. Now just talked with my husband about thier room to do some changes byy beds and do some decor. But her dady also doesnt want that he is saying i cant sleep without my daughter. What should i do?
